The actress, who left Grey's Anatomy after last season, has signed on for two March episodes of NCIS: Los Angeles that could result in a third NCIS series on CBS.

Raver will play Paris, an NCIS special agent and leader of the Red team, a small, mobile group of agents that travels the country investigating crimes. Paris, who has a forensic science degree, is described as athletic, smart and bold and is someone who likes to work alone.

Raver, a veteran of 24 and Third Watch, will join Northern Exposure's John Corbett in the two episodes. Corbett will play analyst Roy Quaid, a former special agent who is the most experienced investigator of the Red team.

The spinoff model has worked well for the NCIS franchise. NCIS: Los Angeles was introduced during two episodes of the original NCIS.
